자동차 BSR의 객관적 평가를 위한 측정방법

The present study reviews the measurement conditions for automotive BSR(Buzz, squeak, and rattle) noise evaluation. Eventhough there already exist standards for measuring sound level and sound quality issues, the inherent requirement are not the same especially in BSR measurements for detection, which sometimes causes confusion. Background noise level and running noise level, measurement location, filtering and/or weighting issues are discussed with illustrations.
